Application filed January 21, 1916 Serial No. 73,450.

zen of the United States, residing at Manchester, county of Hillsboro,State of New Hampshire, have invented an Improvement in Filling-Replenishing Mechanism for Looms, of which the following description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawing representing like parts.

This invention relates to automatic filling replenishing mechanism forlooms ,of the Northrop type in which the supply of fresh fillingcarriers or bobbins is maintained in a rotary battery, feeder or hopperfrom which upon thecall for filling replenishment they are successivelytransferred to the running shuttle.

More particularly the invention relates to filling replenishing looms ofthistype in which a definite relation of the filling carrier rotarily ofits longitudinal axis with respect to the shuttle walls is requisite,because of the use offilling carriers'or bobbins of the generalcharacter illustrated in the patents to William Parker Straw No.908,748, granted December 5, 1908, No. l,053,67 3, granted February18,1913, and No. 1,092,959 granted April 1-4, 1914.- I

The general type of filling mechanism is well known and-familiar andreference may be had to the Patent to E. S. Stimpson No. 664,790 grantedDecember 25, 1900 as an illustration. ofone form thereof. When, however,filling carriers are employed of the character disclosed in theaforesaid patents to Straw, it is desirable that the seats for the to bereplenished.

butts of the filling carriers located inthe periphery of the disk of thehopper instead of being radial as illustrated in the aforesaid patent toStimpson shall be inclined to the radii of the hopper in order to assistin guiding the filling carriers during transfer to the shuttle on thelay which is beating up as transfer begins and to insure the properpositioning of the filling carrier in the shuttle In these types offilling replenishing mechanism the bobbin to be transferred is broughtby the feeding movement of the hopper into contact with a relativelyfixed guiding abutment and during transfer the bobbin is or should be incontact with this abutment in order to direct it properly into theshuttle. The object of the abutment is thus to maintain the bobbinduring transfer in the desired path or line of transfer, but theinvention in its broader aspect is not to be limited to the use of sucha guiding abutment. When the peripheral seats in the hopper are inclinedto the radii the hopper must have a rotary movement until the bobbin haspassed out from the seat in order to maintain the bobbin in guidingcontact with the abutment and the hopper must preferably then be lockedagainst further rotary movement until a predetermined reverse movementof the transfer means has taken place sufficient to preventvInalposition of the parts such for example as the next succeedingbobbin in the hopper coming into engagement with the transfer means. Ifthis rotary movement of the hop per to maintain the bobbin to betransferred in guiding contact with the abutment during transfer doesnot take place the bobbin may ride up on the usual pivoted bobbinsupport located opposite to the abutment or the bobbin may bemispositioned it. or fail to enter the shuttle, thus preventingreplenishment taking place and even causing a smash.

It is the object of the present invention to provide means acting togive the required rotary movement of the hopper to maintain the bobbinbeing transferred in contact with the abutment until the bobbin passesentirely out from its seat in the hopper and also preferably thereuponto lock the hopper against further rotation until such a reversemovement of the transfer means has taken place as to prevent anyimproper operation or positioning of the mechanism. These and otherobjects of the invention will appear I nism embodying the inventionembodied therein.

' In the drawings, Figure 1 1s an end elevatlon partlally in transversesection of a suffici'ent portion of the loom necessary to a disvention;Fig. 4is a view in vertical cross section taken on the line 1-l, Fig. 1.

The general construction of the type of loom illustrated being wellknown and familiar needs no extended description. It includes therotatable battery feeder or hopper comprising parallel disks betweenwhich the filling carriers such as bobbins are mounted in a circularseries. But one of these disks, namely, the disk 1 provided with seats,2 for the butts of the bobbins is illustrated. The hopper is rotatablymounted on the fixed stud 3 rigidly secured to the hopper stand 4 whichis itself secured to the loom frame at one side of the loom. A circularflange 5 on the hopper stand surrounds the disk 1 to protect the headsof. the

bobbins and to retain them in place until they reach substantially theiroperative position, the flange terminating at the points 6 and 7.

The filling carriers or. bobbins 8 illustrated are of the type disclosedin the aforesaid patents to Straw in which the barrel of the bobbin isprovided with a transverse slot or opening to cooperate with a feelerwhereby absence or exhaustion of the filling in the running shuttle isindicated. This requires that the bobbin when placed in the shuttleshall occupy a definite relation rotarily of its longitudinal-axis. withrespect to the walls of the shuttle. For this purpose the butt of thebobbin is provided with a, pair of parallel positioning faces 9 whichdetermine the position of the bobbinin the shuttle. The seats'2 in thedisk-1 of the hopper are accordingly formed with parallel walls and ofsuch width as to fit the butts of the bobbins, and thusretain thebobbins in fixed relation in the hopper.

When transfer of the bobbin from the hopper beginsthe shuttle which isto re-.

ceive the bobbin is on the lay beneath the hopper and the lay-isconcluding its beat up toward-the left, viewing Fig. 1, and hence inorder that the bobbin may more surely enter the bobbin holding orgripping devices in the shuttle in correct position it has been founddesirable toposition the seats 2 in a'direction inclined to the radii ofthe hopper as indicated in the drawing.

'The hopper stand 4 is provided with a relatively fixed abutment 10against which the bobbin to be transferred is brought by the rotation ofthe hopper and during transfer from the hopper the bobbin is guidedagainst this abutment to direct it into the shuttle beneath. The flange5 terminates at the point 7 a considerable distance from the abutment 10but is effectively prolonged by the bobbin support 11 pivoted on thehopper stand at 12. This bobbin support serves to retain thebobbinsnearest the abutment in their seats in the hopper and yields upon thepassage of the bobbin to be transferred to permit its discharge from thehopper.

The mechanism for effecting transfer of the bobbins is illustrated as ofa well known type comprising the transferrer l3 pivoted on a horizontalstud 14 carried by the hopper stand 4:, and provided with a dependingarm 15 through which it is actuated upon the call for fillingreplenishment. The transferrer is normally elevated through the actionof the usual spring 16 and is depressed to effect the transfer movementthrough the usual connections of the depending arm 15. At its free endthe transferrer is provided with a downturned portion 17 to engage thebobbin and discharge it from its seat in the hopper disks.

The hopper is rotated to bring a fresh bobbin into position for transferby suitable mechanism and in the type illustrated this rotation issecured by a dog 18 pivoted at 19 to the transferrer and provided with atooth 2O cooperating with the teeth of a ratchet wheel 21 integral ormoving synchronously with the hopper. Upon the reverse movement of thetransferrer the tooth 20 engaging the ratchet wheel 21 rotates thehopper to bring the leading bobbin of the series in the hopper intocontact with the abutment l0 and thus into position for transfer.

With the bobbin butt seats 2 inclined it follows that as the bobbinduring transfer moves out of its seat it will move away from theabutment 10 and unless the rotation of the hopper is continued tomaintain the bobbin in contact with the abutment until after it leavesits seat the bobbin may ride up on the pivoted bobbin support 11 andthus transfer fail to be effected and a smash caused. The hopper isusually free to rotate but it cannot be depended upon to rotate tosecure the proper operation of the parts. Consequently this inventionprovides a means for securing the rotation of the hopper to maintain thebobbin in contact with the abutment 10 during transfer or until afterthe bobbin leaves its seat.

Filling replenishing mechanism of the type here involved is usuallyprovided with a detent pawl 22. This pawl is provided with a tooth 23engaging the ratchet wheel 21, and its usual purpose is to preventreverse rotation of the hopper. The present invention may, and in thepreferred form illustrated does, make use of this detent pawl as one ofthe elements of the mechanism involved in securing the necessaryrotation of the hopper during transfer. For this purpose in theconstruction illustrated a pawl support 24 is pivoted on a stud 25projecting from the hopper stand and extends rearwardly past the pivot14 of the transferrer. The detent pawl 22 is provided with a stud 26 bywhich it is pivotally mounted'midway the length of the pawl support 24.Hence upon the movement of the pawl support, 24 the detent pawl 22 isgiven a bodily movement while it has in addition its usual pivotalmovement upon the stud 26. In order to operate the pawl support thetransferrer 13, in the construction illustrated, presents rearwardly ofits pivot 14 an arm 27 extending beneath the rearward end of the pawlsupport. Preferably also a yielding connection is provided between thearm 27 and the rearward end of the pawl support 24. For this purpose theend of the pawl support is given a cam shaped recess 28 and the arm 27is provided with a plunger 29 cooperating with said recess 28, andyieldingly held by the spring 30 in a socket in the arm 27. When now thetransferrer 13 in the operation of transfer is moved downwardly intocontact with the bobbin to be transferred the arm 27 is elevated andthrough the yielding plunger 29 and in cooperation with the cam shapedrecess 28 swings the pawl support 24 upwardly about its pivot 25, and bya sort of toggle action bodily moves the detent pawl 22 upwardly thusthrough the medium of the ratchet wheel 21 rotating the hopper andmaintaining the bobbin being transferred in contact with the guidingabutment 10, the spring 30' yielding as required to prevent binding ofthe parts.

In order that the movement of the rotation thus embodied to the hoppermay not be excessive or more than required to effect the desired result,a condition which if permitted would bring the next succeeding bobbin inthe hopper into contact with the transferrer and thus prevent improperpositioning of the parts, it is desirable that the hoppcr should belocked against further rotation until such a reverse movement of thetransferrer has taken place as to prevent any improper operation orpositioning of the mechanism. In the construction illustrated in Figs.1, 2 and 4 this result is secured by means of a brakeengagingfrictionally the periphery of the hopper. For this purpose thepawl support 24 is provided with a brake arm 31 so positioned that whenthe bobbin has passed entirely out from its seat in the operation of thetransfer this brake arm 31 is brought by the movement of the pawlsupport into frictional engagement with the periphery of the hopper disk1 thus locking ferrer arm the spring 30 yields. This brake arm is heldin engagement with the hopper disk until the transferrer arm rises tosuch a position in its reverse movement thatthere is no danger of animproper positioning of the parts.

It is also desirable that positive means shallbe provided for unlockingthe hopper and freeing it to rotation when the necessity for brakingaction has ended. In the construction illustrated this is secured by providing an upward extension 32 on the transferrer in front of the hub 33of the pawl support 24 in which the stud 26 is pivoted. This extensionis so formed and located that as the transferrer rises in its reversemovement to a position where the braking action may be released it comesin contact with the hub 33, and thus swings the pawl support rearwardlyreleasing the brake arm 31 from the periphery of the hopper, and thusunlocking the hopper and freeing it to rotation.

The operation of mechanism illustrated in Figs. 1, 2 and 4 will now beapparent. Through the usual upward or reverse movement of thetransferrer 13 and the engagement of the tooth 20 of the dog 18 carriedthereby with the ratchet wheel 21 the parts have been brought into theposition illustrated in Fig. 1 with a bobbin resting against the guidingabutment 10 and upon the tip of the pivoted bobbin support 11 ready fortransfer. The detent pawl 22 at this time is held in engagement with theratchet wheel 21. Upon the call for filling replenishment the arm 15 ofthe transferrer is pushed rearwardly causing the transferrer to descendand contact with the bobbin therebeneath. This at the same time elevatesthe arm 27 and causes the pawl support 24 to swing upwardly carryingbodily with it the detent pawl 22 which thereupon as the transferrercontinues its downward movement acts to rotate the hopper and maintainthe bobbin in contact with the guiding abutment. When the bobbindepressing the bobbin support 11 has entirely freed itself from its seatthe friction brake 31 coming into contact with the periphery of thehopper locks it against further rotation and the further descent of thetransferrer acting against the spring 30 causes no further movement ofthe detent pawl. Upon the reverse movement of the transferrer undercontrol of its spring 16 when it has reached a position where there isno danger of the next succeeding bobbin coming into contact with it orthe parts being otherwise mispositioned the extension 32 comes againstthe hub 33 of the pawl support and swings the pawl support 24 rearwardlyreleasing the brake 31 from the hopper disk and thus enabling thetransferrer on completion of its upward or reverse movement actingthrough the dog 18 again to rotate the hopper to insure the presence ofthe next bobbin in position for transfer. Thus the bobbin beingtransferred is carried positively and accurately downward in contactwith the guiding abutment 10 out of its seat and in proper position toenter the shuttle beneath on the lay to be replenished.

The construction illustrated in Fig. 3 is the same in all respects asthat already described except that a different means is illustrated, asan embodiment of the invention for locking the hopper against undesiredor further rotation until the predetermined reverse movement of thetransferrer has taken place. In the construction illustrated in Fig. 3 ameans is employed for entering a recess such as the space between theteeth of the ratchet wheel 21 and thus positively locking the hopperagainst further. rotation at the requiredtirne. As an example of suchmeans the pawl support 24 has projecting-forwardly from its hub 33 alocking arm 34 so shaped and positioned that when the transferrer in itsdownward movement of transfer has cleared thebobbin from its seat in'thehopper the end of this locking 7 arm-will enter a space between two ofthe teeth inthe ratchet wheel 21, and thus lock the hopper againstfurther rotation. Upon the reverse movement of the transferrer' to therequired extent the extension 32 will as before contacting with the hub33 swing the pawl support 21 rearwardly and thus withdraw the lockingarm 34 from engagement with the teeth of the ratchet wheel 21 againleaving the hopper free to rotate.
